I recently came across a thermal imaging camera that I really don’t like. It’s partly about the image quality, and much more about different user experience factors.
In order to provide helpful feedback to the company, I whipped out my favorite thermal imaging camera for a quick comparison, and aimed them both at an electrical circuit breaker panel box.
It then made sense to me to reach for every single thermal imaging camera at my disposal for an even wider comparison. I’ve been meaning to do this for a while, and finally had a good reason to do so.
There are a few “imaging thermometer” devices that I can’t find at the moment, but the one I did find and use should give you a good indication of what you can expect from similar tools.

All images are straight out of their respective cameras, with the only editing being for size and highest quality jpeg conversion. Images are in the order of least expensive product to most expensive.
Rainbow color palettes were used where possible.

Flir TG165 Imaging Thermometer
Flir’s TG165, which I reviewed last year, is designed to pinpoint trouble areas for temperature measurements. It’s not a true thermal imaging camera, but can provide far more insight than a simple IR thermometer.

Flir C2 Compact Thermal Imaging Camera
The Flir C2 is a pocket-sized and relatively affordable thermal imaging camera. It came out earlier this year, and although engineered with an 80 x 60 px sensor, Flir’s MSX image contrast enhancement technology does a great job of raising the image quality.

Flir E4 Thermal Imaging Camera
I bought my Flir E4 last year and used the community enhancement to unlock the full higher resolution of the built-in sensor. It ships as an 80 x 60 pixel device, but the conversion instructions were simple and allows the E4 to create images with 320 x 240 px thermal resolution.

This is a reminder that you can’t always trust what you see on camera. If my hand wasn’t in the frame of this image, then the reflection on the panel would have stood out a lot more against the background.
Even in complete darkness, infrared light emitted from your body and other heat sources with bounce off of reflective objects. This can give a false sense that something is hotter than its surroundings when it’s not.

Milwaukee Thermal Imaging Camera (M12, 160 x 120 px resolution)
Milwaukee has 2 thermal imaging cameras now – the original M12 model, and a new 7.8KP thermal imaging camera that’s coming out soon. This is the original, with 160 x 120 px resolution. The new model has a 102 x 77 px sensor.
This image was taken using Milwaukee’s BETA firmware, and about a half hour after the others, which is why the breaker pair on the lower right side of the panel looks different.

Fluke Ti110 Thermal Imaging Camera
Fluke’s Ti110 is a somewhat different beast than the other models, and has video recording capabilities and smooth lens focusing. Like the Milwaukee model, it features a 160 x 120 px thermal sensor, but software-wise it’s much more sophisticated.
Fluke’s IR Fusion feature in this model creates a somewhat blended image, with the full thermal resolution image being nested at the center of a visual image for easier guidance.

Flir E60 Thermal Imaging Camera (pre-MSX)
I was able to borrow a Flir E60 a couple of years back, before it was equipped with Flir’s MSX image enhancement technology. At the time it did offer WiFi tablet connectivity, but was a little buggy and deleted some images.
Even so, the E60, a 320 x 240 px device, delivered phenomenally good thermal image quality. While I had the good thinking to take an image of the circuit breaker panel, I used the “iron” palette instead of rainbow.
So… I opened up Flir Tools, their free software, and changed the color palette to rainbow:
This image is not straight out of the camera, but uses the same thermographic data, and so it would have appeared like this if I used the rainbow palette instead of iron at the time of image capture.
I also captured an image with high contrast rainbow palette setting.
Price: $6995
Newer E60’s offer built-in MSX image enhancement technology. Since I returned this loaner sample years ago, I can’t show you what the image of a new E60 would look like.

Conclusion
My goal here was to show what you could expect to see at different thermal imaging camera image resolutions. The more you spend, the more you get, with respect to thermal sensor size and also built-in features. But you can still get respectable image quality and useful features for under $1000.
